  • the present invention relates to a method for installing a solar cell module.
  • solar cell modules have been installed on the roof of buildings, such as residential houses and carports.
  • Examples of a known method for installing a solar cell module on a roof include a method comprising forming a rack on a roof in advance, and attaching and fixing a solar cell module to the rack.
  • Solar cell modules usually have a structure in which the edges are surrounded by an aluminum frame (frame material).
  • a method for installing a solar cell module on a roof the method comprising fixing with clamps, bolts, or the like, a solar cell module to angle bars that are assembled into a lattice, has been frequently used.
  • Patent Literature (PTL) 1 discloses a support structure of a rack in which multiple vertical members and horizontal members are assembled with bolts or the like.
  • the conventional method for installing a solar cell module on, e.g., the roof of a residential house or a carport by using a rack would, for example, require a worker to install a solar cell module on the roof and fix the module with a fixing tool, such as a bolt or a clamp.
  • a fixing tool such as a bolt or a clamp.
  • the roof which does not always have sufficient strength, may be damaged by the weight of the worker and the solar cell module when the worker is on the roof carrying the solar cell module, and since there is a high risk of the worker falling off the roof.
  • An object of the present invention is to provide a method for installing a solar cell module, which enables easy installation of a solar cell module on a rack that is light enough to reduce the load on the roof, and which also enables a worker to install a solar cell module without climbing on the roof.
  • the present inventors conducted extensive research to solve the above problems, and found that the above object can be achieved when a solar cell module protected by a frame formed of a material containing a resin is installed using rails with a specific shape.

  • the solar cell module 16 comprises, on at least a portion of the outer periphery, a frame 14 formed of a material containing a resin.
  • the rack 20 includes multiple rails 18 each having a groove 19, and the grooves 19 of a pair of the rails 18a and 18b are disposed to be opposed to each other.
  • the frame 14 is configured to cover the entire periphery or a portion of the periphery of the solar cell 10. As described later (see Figs. 1(c) and 1(d) ), at least one pair of side edges of the solar cell module 16 is to be fitted in the grooves 19; therefore, the frame 14 is preferably provided on at least one pair of side edges among the four sides of the solar cell 10, and the frame 14 is more preferably provided on all of the four sides (i.e., the entire periphery) of the solar cell 10.
  • the type, size, etc. of the solar cell 10 are not particularly limited, and known solar cells can be widely used.
